.net 使用ManagementObjectSearcher 获取cpu、mac、硬盘sn

需要按照对应的nuget包: System.Management

获取cpu信息

ManagementClass mc = new ManagementClass("Win32_Processor");
ManagementObjectCollection moc = mc.GetInstances();

string strCpuID = null;
foreach (ManagementObject mo in moc)
{
    strCpuID = mo.Properties["ProcessorId"].Value.ToString();
    break;
}

return strCpuID;

获取mac信息

ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * FROM Win32_NetworkAdapterConfiguration");
ManagementObjectCollection queryCollection = query.Get();
string mac = string.Empty;
foreach (ManagementObject mo in queryCollection)
{
    if (mo["IPEnabled"].ToString() == "True")
        mac = mo["MacAddress"].ToString();
}
return mac;

获取硬盘sn有两种方法

第一种 – 使用此方法获取到的待选数据较少所以速度稍快一些，但整体性能与第二种并无量级上的区别

string sn = string.Empty;
var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
foreach (ManagementObject wmi_HD in searcher.Get())
{
    foreach (var item in wmi_HD.Properties)
    {
        if (wmi_HD.Properties["SerialNumber"] != null)
        {
            sn = wmi_HD.Properties["SerialNumber"].Value.ToString();
            break;
        }
    }
}
Console.WriteLine(sn);

第二种

string sn = string.Empty;
ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
foreach (ManagementObject wmi_HD in searcher.Get())
{
    if (wmi_HD.Properties["SerialNumber"] != null)
    {
        sn = wmi_HD.Properties["SerialNumber"].Value.ToString();
        break;
    }
}
Console.WriteLine(sn);
